2MP Smart Dual Light Dome IP Camera – DS-2CD1123G2-LIU (2.8mm)

The 2MP Smart Dual Light Dome IP Camera – DS-2CD1123G2-LIU is an advanced surveillance solution designed to deliver high-quality video, intelligent lighting, and reliable performance for both residential and commercial security applications. Built with the latest imaging and compression technologies, this camera ensures superior clarity, efficiency, and adaptability in a wide range of environments.

High-Definition Imaging

At the heart of this camera lies a 1/2.9″ Progressive Scan CMOS image sensor, capable of capturing crisp, clear, and detailed footage with a maximum resolution of 1920 × 1080 (Full HD). This ensures excellent video quality whether monitoring small indoor spaces or expansive outdoor areas. The wide dynamic range of the camera allows it to handle challenging lighting conditions, delivering balanced images even in scenes with strong contrasts of light and dark.

Flexible Lens Options

The camera comes with fixed focal lens options of 2.8mm and 4mm, giving users flexibility depending on their monitoring needs:

• 2.8mm lens: Provides a horizontal field of view of 103°, vertical 56°, and diagonal 121°, making it ideal for wide coverage areas such as entrances, halls, and parking lots.
• 4mm lens: Offers a horizontal field of view of 83°, vertical 44°, and diagonal 99°, suitable for focusing on narrower, more specific zones where greater detail is required.

Additionally, the lens design supports angle adjustment with pan (0°–355°), tilt (0°–75°), and rotation (0°–355°), allowing precise positioning during installation.

Smart Dual Light Technology

One of the standout features of this model is its Smart Hybrid Light technology. The camera is equipped with both IR (infrared) and white light illuminators, which can be automatically adjusted based on environmental conditions. At night or in low-light environments, the IR LEDs provide discreet monitoring with a range of up to 30 meters. When motion is detected or full-color detail is needed, the white light activates to deliver vivid, color-rich images.

This intelligent dual-light design ensures that users benefit from both covert infrared surveillance and color monitoring for enhanced identification of people and objects.

Advanced Video Performance

The camera supports smooth video streaming at:

• Main stream: Up to 25 fps (PAL) or 30 fps (NTSC) at 1080p and 720p resolutions.
• Sub-stream: Up to 25/30 fps at lower resolutions (640 × 480, 640 × 360).

It offers versatile video compression formats including H.265+, H.265, H.264+, H.264, and MJPEG, ensuring efficient storage use without compromising video quality. With bit rate control modes (CBR and VBR), users can optimize performance depending on bandwidth and storage needs.

The Region of Interest (ROI) feature allows focused video quality on critical areas within the scene, ensuring efficient use of network and storage resources.

Built-in Audio Support

For enhanced situational awareness, the camera is equipped with a built-in microphone, enabling real-time audio monitoring alongside video. Features like environmental noise filtering ensure clear voice capture, while support for multiple audio compression formats (including G.711, G.722.1, G.726, MP2L2, PCM, and AAC-LC) allows integration into different recording systems.

Network and Storage Features

The DS-2CD1123G2-LIU is designed with scalability and convenience in mind:

• Supports up to 32 simultaneous users with three defined user levels (administrator, operator, user).
• Compatible with iVMS-4200 and Hik-Connect, enabling remote monitoring and management from PCs or mobile devices.
• Offers on-board storage support up to 512 GB via microSD card (optional), allowing local recording even without a network connection.
• Compatible with major web browsers including IE10, IE11, Chrome 57.0+, and Firefox 52.0+.

Efficient Compression Technology

Thanks to H.265+ and H.264+ advanced compression technologies, this camera reduces bandwidth usage and storage requirements significantly compared to traditional encoding methods. This efficiency allows longer retention periods and lower operating costs without compromising image quality.

Robust and Reliable Design

The dome design offers durability and discretion, making it suitable for both indoor and outdoor installations. The camera’s materials and engineering are built for long-term reliability, with protection against harsh environments. Its compact design also allows easy integration into various architectural settings without being intrusive.
